CAS: 2181774-46-7

PAIRED PRODUCT AVAILABLE: alpha-L-iduronidase Enzyme, FI1793834MU-alpha-L-iduronide-2-sulphate (M2) is a fluorogenic substrate of iduronate-2-sulphatase (IDS), used in a 2-step assay coupled with alpha-L-iduronidase. The assay is used in biochemical testing for Hunter syndrome (mucopolysaccharidosis II / MPS II). In a first step, IDS from biological samples cleaves the sulphate group from M2. In a second step, exogeneous alpha-L-iduronidase which cleaves the 4-MU moiety is added to the reaction, resulting in release of a fluorescent signal (Ex 360 nm / Em 455 nm). The reaction is stopped by the addition of sodium carbonate.
